Kyrielite

I've had this vn for a while now but only recently (I believe after the windows 10 anniversary update or one of the smaller updates following it) have I been experiencing this issue: So I was wondering if others were experiencing this issue and how to potentially solve it? I know that the best option would probably be to roll back to a version before the update but I thoughtlessly deleted the windows.old file as I was needing space on my C drive. So if there are any other solutions to this error, I would very much appreciate knowing them very much! I have also tried to run it in compatibility mode and also reinstalling but the same error occurs.
